There are available different types of metal detectors in the market to suit the specific needs of diverse industries. These detectors are designed to indicate the metal presence in non-conductive materials. It includes liquids or oils, rubber, textiles, wood products, powders, plastics, concrete, glasses, ceramics, etc. Doing some research will allow you to know more about them.
Use of metal detectors
Generally, Industrial Metal Detector is used for verifying tramp metal absence or to determine cleanliness in bulk or continuous, recycled materials or products. A few applications include detecting metal chips, especially in pharmaceutical preparations or powders, staples or nails in wood. It also helps with needs used in fabric sheets and metal caps for crushed glass.
Metal detectors are used for verifying the location and presence of metal like piping behind walls, buried electrical lines, or metal rebar reinforcement in concrete. Airport metal detectors equally find great use to detect various types of weapons, bombs, knives, and guns. The detectors meant for security applications are used for detecting metallic items that any person might try to smuggle out or inside the secure facility.
Know the different types
There are different types of metal detectors designed to perform specific purposes. It will be necessary to know about them to make well-informed decisions.
- Portable metal detectors: The portable detector is designed to be used on-site, for commercial and residential purposes. Also are commonly available vehicle-mounted metal detectors. Although not considered technically portable these detectors are fixed at a particular location. It is possible to move the whole device to the desired site or location where there is required detection technology.
- Inline or Fixed metal detectors: It is possible to mount modular metal detectors on the doorway, under a conveyor or in any other area where metal object detection is warranted. These devices are not designed to be free-standing. They might include or not come with a mounting kit. The most often used for security applications is walk-through metal detector. Their purpose is to detect metals that are carried through the passage or doorway.
What does the conveyor system do?
Metal conveyor detector systems are designed to trace metal amounts present. This is at the place where the conveyor is used to introduce the media or via the pipeline. The other types detect metal in free-flowing or gravity-fed media. Concerning performance, capabilities, optional features, and specifications, metal detectors meant for industrial usage tend to differ.
Detecting various elements
HMD (Hot Metal Detector) is designed to detect meals having temperatures exceeding the cure point. Lead, brass, and aluminum can be detected using non-ferrous metal detectors. Various types of metals segmented as non-magnetic along with alloyed steels can be detected using non-magnetic metal detectors. Sensitivity, sensing diameter or width across mass flow or throughput, velocity or speed, and interface type is considered to be vital specifications to be taken into consideration.
Features to look for
When seeking metal detectors, do check out a few features. It includes product-effect compensation or background correction, location marking or mapping, material or product rejection, programmability, sorting gates, shallow-depth sensing, and sensitivity adjustments. Also are available with a touch-screen, contact-sensitive interface.
